x12saandClaude Sonnet 5 f93e591227 feat(flomni): split omny_panda into two devices, fix free-running completion check
CI for csaxs_bec / test (push) Successful in 2m13s
Mode A (per-gate aggregate) and Mode B (continuous raw-sample) need
different PandA hardware layouts and can't run simultaneously, so
omny_panda is now two device config entries in ptycho_flomni.yaml:
omny_panda (legacy, kept commented as the restore reference) and
omny_panda_continuous (raw_stream_mode: true, enabled).

Also fixes on_complete for the continuous case. PCAP.CAPTURED can't be
used to detect end-of-acquisition on this layout: CLOCK1 drives
PCAP.gate/trig continuously, so the captured count never naturally
stops increasing while armed -- the previous settle-based wait would
have just run out its timeout. COUNTER1 (frame_counter) instead counts
completed exposures directly (triggered on the detector-trigger's
falling edge), so PandaBoxOMNY now waits for it to reach the exact
expected num_points * frames_per_trigger, mirroring the legacy
exact-count check instead of guessing when capture has "settled".

x12saandClaude Sonnet 5 3012cd3154 fix(flomni): mask gate_detector_active to its own bit, record confirmed PandA wiring
TTLIN1 (detector trigger) drives both COUNTER1 (frame_counter) and the
PCAP.BITS0 gate-bit capture, confirmed 2026-09-15 against the omny-panda
hardware via TTLIN1.VAL.CAPTURE_WORD?/OFFSET? (PCAP.BITS0, bit 0).

PCAP.BITS0 is a shared 32-bit word -- other captured bit_out signals may
occupy other bit positions of it, so the raw word is not itself a clean
0/1. PandaBoxOMNY now masks gate_detector_active down to bit 0 before
publishing it, instead of trusting the whole word.

Also records the confirmed free-running setup in the developer docs: all
four encoders plus both FMC_IN channels switched to raw Value capture,
CLOCK1 driving continuous PCAP gate/trig, and the initial 100 Hz test
rate.

x01dcandClaude Sonnet 5 82ecab4c21 feat(flomni): add continuous free-running raw-sample mode to PandaBoxOMNY
CI for csaxs_bec / test (push) Successful in 2m14s
Adds an opt-in raw_stream_mode to omny_panda alongside the existing
per-gate averaged burst acquisition, so a burst window can instead be
captured as continuous raw samples plus a detector-gate bit and a
monotonic frame counter for completeness checking. Client-side
coalescing bounds the message rate to the BEC message bus regardless of
PandA's own network-frame batching, and completion uses a settle-based
check since an exact expected sample count isn't predictable for
continuous capture. Defaults to off, preserving today's behavior
exactly; hardware wiring/layout and the raw data schema are documented
under docs/developer/ pending PandA hardware access to configure and
validate against.
